Description
Summary:Background Interstitial lung diseases (ILDs) comprise a group of more than 200 different subtypes. They vary widely in terms of incidence, prognosis and treatment, yet real-life data from Germany are sparse.Methods The prospective Exploring Clinical and Epidemiological Characteristics of Interstitial Lung Diseases (EXCITING)-ILD registry included patients with all different ILD subtypes from different healthcare settings. Follow-up ranged from 36 months to 5 years. Data were analysed descriptively. Baseline characteristics, diagnostic and treatment information are presented as absolute numbers and percentages. The Wilcoxon signed-rank sum test was used to quantify differences between groups. Line plots and bar plots were used for graphical presentation.Results A total of 601 patients (60.7% men, mean age 64.3 years) from 32 centres were included in the EXCITING-ILD registry. The most common subtypes were sarcoidosis with 26.6% (n=160) and idiopathic pulmonary fibrosis (IPF) with 25.3% (n=152). Pulmonary hypertension was present in 8.7% of patients (n=52), with high incidences in connective tissue disease-associated ILD (16.3%) and pneumoconiosis (27.3%). The mean forced vital capacity was 76.4% predicted, and the mean DLCO-SB (diffusing capacity for carbon monoxide) was 54.1% predicted. The mean time to diagnosis was 38.8 months (SD 64.4) and was significantly shorter when the diagnosis was made after multidisciplinary discussion (31.6 vs 49.2 months, p<0.001). The frequency of surgical lung biopsies decreased over time in the registry, whereas the proportion of cryobiopsies showed a notable increase. In IPF, the number of patients treated with antifibrotics increased from 35.2% before 2015 to 48.4% in 2019.Conclusion The EXCITING-ILD registry describes the frequency of ILD subtypes, ILD-related impairments, selected comorbidities and diagnostic and treatment patterns in a representative German population.
